I've taken a look at the source a while ago but the make file is a bit complicated for me, it uses a lot of advanced Make syntax. The 1st hurdle I found was what seems to be a Perl script. There's various versions of Perl available on Aminet but I didn't take a look on setting them up. There probably would have to be modifications of the make file on the way it calls the perl script on 3.x too.
